Stopped account

Afternoon. My mother and my cousin rendered service at Arts and Culture last month. My mother then transfered an amount of R220 000 in her Capitec account to do transfers to the people who helped her. In that we needed R40000 Cash as some people preferred to be given the money at hand so she transfered R30500 in my account. Since the maximum withdrawal limit is R10000 for withdrawal I then split the money between my sister and my wife's accounts to be able to withdraw it. Later in the evening our accounts were placed on hold for suspicious transactions. My mother provided both proof of payments from the department of Arts and Culture along with the standard bank business account one, now we are told to wait as it is being investigated and my salary has been paid into that account and I have to pay my obligations as I have children in school. Why should the process prolong if we provided all necessary documents? Why not hold the amount from yesterday and give allowance to my salary? I would understand if we didn't provide any documentation but the fact that Capitec has the documents required to investigate shouldn't be such a hassle unless the bank is accusing us of falsifying those documents. I am really disappointed with this treatment
